We told you about the Boonana Trojan Mac virus that was discovered by SecureMac just yesterday. SecureMac has now completed its initial analysis of the virus and has new information about it, as well as a removal tool if you believe your Mac is infected.

According to the company’s security bulletin, “The initial infection vector of the Boonana trojan is through a message on social networking sites similar to “Is this you in this video?” which includes a link to an external site. Upon clicking the link, a java applet will attempt to load in the user’s web browser. During our testing, the malicious Java applet communicated with a Command & Control server, and presented an installer window at a random time after accessing the malicious site. This installer did not indicate that it had been downloaded from the web which indicates it is avoiding the quarantine flag typically set by programs such as Safari.”

This virus is still listed as a critical security threat due to the fact that the control servers are still operational. SecureMac notes that this means that servers could be gathering information from infected computers like IP Addresses, and potentially the modification of sudoers file that would allow passwordless access to any potentially infected machines. It is thought that this trojan virus could be used for control purposes.

“In many cases, especially with botnets, the malware might not initially exhibit malicious behavior, but can become active at any time as the command and control servers are updated,” notes SecureMac in the updated bulletin.
